The new film co-stars Tom Hardy, as Bane - described in this character biography as one of "Batman's most deadly, powerful foes."

Aren't they all? The description of his character below could be considered a spoiler.

The bio says that Bane was son of a Caribbean revolutionary and spent his childhood in prison where he was injected with an experimental drug that gave him super human strength.

He goes on to break Batman's back, in the comic book narrative ("Knightfall," Batman 497) which could explain the trailer's hospital scenes. The film's title could refer to some kind of "Rocky"-like comeback. But there is no indication the movie will follow this storyline.

Hardy also starred in "Dark Knight" director Christopher Nolan's "Inception," as did Joseph Gordon-Levitt, who also appears in the new film.
